. HANGER FOR SPLEED-CHANGERS.

SPECIFICATION formingpart of Letters Patent No. 753,406, dated March 1,1904.

Original application filed Augiist 3, 1903, Serial No. 167,973. Dividedand this application filed December 9, 1903. Serial No. 184,373. (Nomodel.)

To all whom it may concern:

Be it known that We, ERNEST J. LEES, a citizen of the United States,residing in Warren, W'arren county, Pennsylvania, (post-office addressWarren, Pennsylvania,) and EDWARD L. AIKEN, residing in EastOrange,EsseX county, New Jersey, (post oflioe address No. 643 Springdaleavenue, East Orange, New Jersey,) citizens of the United States, haveinvented certain new and useful Improvements in Hangers forSpeed-Changers, of which the following is a specification.

This invention pertains to improvements in hangers for speed-changers,and will be readily I 5 understood from the following description,

taken in connection with the accompanying drawings, in which Figure 1 isa side elevation, Fig. 2 an end elevation, and Fig. 3 a bottom view, ofa hanger embodying our invention.

In the drawings, 1 indicatesa shaft, and 2 accompanying shaft, the twoshafts representing a pair between which motion is to be transmitted atadjustable rate; 3, an expan- 2 5 sion-pulley carried by shaft 1; 4, anexpansion-pulley carried by shaft 2; 5, a belt engaging the two pulleys;6, the journal-boxes of the shafts; 7, lever-andgear mechanism foradjusting the diameters of the expansion- 3 pulleys, the details ofwhich mechanism need not be here explained, as they are not hereinclaimed; 8, a hanger for each of the journalboxes; 9, the top flanges ofthe hangers; 10,

' side flanges for the hangers, these side flanges being disposed atright angles to the topflanges and serving to form juncture-seatsbetween the two united hangers of a pair, and 11 jointbolts, shownasengaging the side flanges and uniting together the two hangers of apair.

The two expansion-pulley devices and their hangers, associated asillustrated in the drawings, constitute a self-contained speed-changingdevice. This speed device may as a whole be bolted to an overheadsupport or to a machine-frame or other object, or, if desired, the twodevices may be separated from each other at the joint between the sideflanges of the hangers, and each may then be bolted separately to anappropriate support. In thus being bolted to place independently of eachother they may be secured bymeans of either the top flanges 9 or theside flanges 10. If top flanges 9 and side flanges 10 be counterparts ofeach other as regards their sizes and location of bolt-holes, it ismanifest that the side flanges of the hangers of one expansionpulleydevice may be bolted to the top flanges of the other one. It istherefore seen that one of these expansion-pulley devices may be usedalone quite independent of the existence of the other one or that thepair of them may be used secured directly together in severalrelationships or that a pair of them may be used separated from eachother and secured in varying relationships to each other. 5

This application is a division of an application filed by us August 3,1903, Serial No. 167,97 3.

We claim as our invention- 1. In a hanger for speed-changers, the com- 7bination, substantially as set forth, of a shaft, a pair ofjournal-boxes thereon, and a hanger for each journal-box, each hangerbeing provided with a pair of attaching-flanges at right angles to eachother.

2. In a hanger for speed-changers, the combination, substantially as setforth, of two shafts mounted parallel with each other, anexpansion-pulley on each shaft, an independent pair of hangers for eachshaft, and means for separably connecting the hangers of one shaft withthose of the other shaft.

3. In a hanger for speed-changers, the combination, substantially as setforth, of two shafts mounted parallel with each other, an 5expansion-pulley on each shaft, an independent pair of hangers for eachof said shafts, and attaching-flanges upon said hangers in position topermit of the hangers of one shaft being separably bolted to the hangersof the other shaft. V

4. In a hanger for speed-changers, the combination, substantially as setforth, of two shafts mounted parallel with each other, an

, expansion-pulley on each shaft, an independent pair of hangers foreach shaft, flanges upon said hangers in position to permit of thehangers of one shaft being separably bolted to the hangers of the othershaft, and flanges disposed upon said hangers at right angles to thebefore-mentioned flanges.
